Building Instructions

Background

To live away from earth, it would help if we were good at detecting and mining resources under the surfaces of other planets, moons, asteroids, and even comets.

Mission

The robot needs to get all the core samples out of the core site model, then it has options for what to do with them as described here, and in mission M03.

Scores

• Move all four core samples so they are no longer touching the axle that held them in the core site model: 16
• Place the gas core sample so it is touching the mat, and completely in the lander’s target circle: 12 OR
• Place the gas core sample completely in base: 10
• Place the water core sample so it is supported only by the food growth chamber: 8
• Possible Scores: 0, 16, 24, 26, 28, 34, 36

Scoring Requirements

• Results must be visible at the end of the match.

Background

For rovers in other worlds, getting stuck is definitely not okay! Teams of rovers can help each other, but a lone rover needs to be very careful.

Mission

The robot or whatever agent-craft it sends out needs to cross the craters model completely, by driving directly over it. Not near it. Not around it.

Scores

• Robot or agent-craft crossed the craters model completely: 20
• Possible scores: 0, 20

Scoring Requirements

• All weight-bearing features of the crossing equipment must cross completely between the towers. > Only allowed method. Must be observed by the referee.
• The crossing must be from east to west, and make it completely past the flattened gate. > Only allowed method. Must be observed by the referee.

Background

Gardening is easy, right? You just need a truckload of rich soil, some rain, sun, fertilizer, helpful bugs, CO₂ and a rake but what if you were orbiting Neptune, in a room the size of a minivan?

Mission

Move the push bar the right distance at the right speed, to get into the green scoring range.

Scores

• Spin the food growth chamber’s colours so the grey weight is DROPPED after green, but before tan, by moving the push bar: 16
• Possible scores: 0, 16

Scoring Requirements

• The result must be visible at the end of the match.
• Spin the food growth chamber’s colors must be spun by moving the push bar. > Only allowed method. Must be oberserved by the referee.

Background

If a satellite doesn’t have the correct velocity and distance from earth, it can fall, drift away, fail to function or get destroyed by debris. Propulsive adjustments need to be performed with precision.

Mission

The robot needs to move one or more satellites to the outer orbit.

Scores

• Move any part of a satellite on or above the area between the two lines of the outer orbit: 8 each
• Possible scores: 0, 8, 16, 24

Scoring Requirements

• Result must be visible at the end of the match.

Background

Our Lander doesn’t have working parachutes, thrusters, or cushions, but one important feature is realistic … it’s very fragile.

Mission

Get the lander to one of its targets intact, or at least get it to base.

Scores

• Move the lander to be intact, touching the mat, and completely in its target circle: 22 OR
• Move the lander to be intact, touching the mat, and completely in the northeast planet area: 20 OR
• Move both parts of the lander completely into the base: 16
• Possible scores: 0, 16, 20, 22

Scoring Requirements

• The result must be visible at the end of the match.
• The lander is “intact” if its parts are connected by at least two of its four tan location axles.

Background

Though spacecraft travel crazy-fast, even the shortest trips involve a lot of time for the traveller’s body away from labour and recreation, which is bad for the heart and lungs.

Mission

The robot needs to repeatedly move one or both of the exercise machine’s handle assemblies to make the pointer advance.

Scores

• Get the pointer tip completely in orange, or partly covering either of orange’s end-borders: 22 OR
• Get the pointer tip completely in white: 20 OR
• Get the pointer tip completely in grey, or partly covering either of grey’s end-borders: 18
• Possible scores: 0, 18, 20, 22

Scoring Requirements

• Advance the exercise machine’s pointer along its dial by moving one or both of the handle assemblies. > Only allowed method. Must be observed by the referee.
• Results must be visible at the end of the match.

Background

It is amazingly expensive to send heavy stuff like construction material into space, so scientists and engineers are instead learning how to print what they need in space, using available extraterrestrial elements.

Mission

The robot needs to get a regolith core sample and place it into the 3D printer, which will cause the 2 × 4 brick to pop out. The ejected 2 × 4 brick can then be delivered elsewhere for more points.

Scores

• The 2 × 4 brick ejected and completely in the northeast planet area: 22 OR
• The 2 × 4 brick ejected and not completely in the northeast planet area: 18
• Possible scores: 0, 18, 22

Scoring Requirements

• Results must be visible at the end of the match.
• Eject the 2 × 4 brick by placing a regolith core sample into the 3D printer. > Only allowed method. Must be obserserved by the referee.

This WRO robot is designed to collect a lot of ping pong balls in its container. It's built with LEGO Mindstorms EV3 45544 and 45560 sets. These are the LEGO Educational sets. The robot has two chains that collect the balls and push them into the container attachment. This is one of the larges robots we've uploaded at FLLCasts yet. You could learn a lot by following the building instructions and paying attention to the details of how this robot is built. All the alignment, all the connections. Really beautiful.  

The first of a series of attachments that we add to a World Robotics Olympiad LEGO Mindstorms Robot. The attachment is an example for collecting ping-balls. The robot and the attachment are in the same construction. The attachment is a base for a container that could be extended.

 

A chassis built with LEGO Mindstorms EV3 parts designed for World Robotics Olympiad

This is a ping-ball containing attachment for a World Robotics Olympiad. The attachment is building with LEGO Mindstorms EV3 parts. It is tiltel so that it is easier for the balls to fall off at certain points, which was part of the missions at the 2015 cmpetition. 

Robot for collecting ping pong balls used in the World Robotics Olympiad competitions. It is constructed with LEGO Mindstorms EV3

This is one of the robots used in World Robotics Olympiad. It uses chains to move ping pong balls out of a container.

LEGO Mindstorms Robot Base for a high placed attachment for containing ping pong balls. It is interesting how the balance is achieved with such an attachment. It was only one of the version in a series of LEGO Mindstorms Robots for World Robotics Olympiad.

Building instructions for a Robot Grabber used in the World Robotics Olympiad competition runs. The grabber is build with LEGO Mindstorms EV3. The base of the robot is available at /materials/69-wro-robot-2014-elementary 

Building instructions for a safe mechanism. The medium motor can be used for dialing in the key lock. The brick buttons can also be used for a pin code input.

One of the large motors unlocks the latch, the other one opens up the lid of the safe.

Building instructions for the catapult that could be placed over the LEGO Mindstorms EV3 Brick. The idea of the catapult it to throw objects. The fact that it is over the brick makes it very convenient to place the motors below the brick and to use the Catapult. 

This robot construction itself was used in the FIRST LEGO League Senior Solutions competition

Building instructions for the robot used in WRO 2014. It is a small robot with two light sensors and could be used for collecting elements. 

The robot is built from LEGO Mindstorms EV3 parts.
